The top ofwthexreceptacle is closed, oropen, as may` be preferred, and the material fed into it inanyconvenient manner.

i. The receptacle comprises' adetachable tip 2l, through which passesthe outlet 19 asshown inr `the drawings. This tip is composedfofrigid.material,preferably of hardenednietal `and comprises, `for apurpose hereafter described, :a apart, or faceplate, having asubstantially plane downwardly presented surface 21' extendingannularly, and radially icutwardly, from and lcompletelysurrounding saidoutlet, and has also a downwardly extending tubular flange portion 2lHhaving `an. angular edge, 21', con'- centric with, and closelysurrounding' the path of the outlet 19. The inner surface of the iiangeconstitutes a part .of the inner surface of the outlet(see Figs. 2 and3).

Underneath the. outlet 19 I 'provide a movable,` a. 6. vertically`reciprocable, can support, 29, (Fig. 1)', which` comprises fa. leg 29*slidably mounted ofthe framed?. ApinQQT, carried bythe leg,isheld-slidably in a lslot 32 located in to,the.,frame. u i

This. `punch isfreciprocated by aid'of allink, or

The normal position of this valveis that shown in Fig. 2, and it is returned thereto and held therein bya retractile spring 56, vconnecting the arm 54 with the frame F. Thevalve 53, is rotatably mounted` in a stationary cylindrical'shell orseat 57 ,carried by the frame Fk to which it is joined by the union 57.An expansile spring 58, bears against the union and the valve to keepthe latter properly seated. The valve 53,*comprises a stem 53Vcontaining, as does the valve, a concentric bore, or air duct 53, whichis connected by laid of `a rubber hosev59, or other unrigid connection,with any preferred air-exhausting appara- I tus (not shown).V

The lvalve 53, contains a by-pass for the material, z'. e. an eccentrictransverse bore 59, whichcommunicates with the outlet 19 when the yvalveis in its Fig.,2. Y

The valve also contains a radial bore, or channel 60, communicatingwith, its concentric bore, or air duct, 53" and which also communicateswith a lateral enlargement, 19', of the outlet 19 ,when the valve hasbeen oscillated by the cam 55 to the position shown in Fig. 3.

Operation: The valve and the punch being in the positions shown-in Fig.2, and the can suitably positioned on the then depressed support 29, sothat the opening, or top, of the can is concentric with the outlet 19 anormal position shown in Vsingle rotation kof the shaft 30, serves to-force the'can up against the tip 21, thereby causing vthe punch 48,'topuncture the head, or to enlarge a previously made opening therein.VThis results in distortingy the sheetmetal and producing an air-tightjoint betweenit'and the receptacle 19, as will be apparent and isvalsomore fully described in my said Patent No. 1,373,275. The punch is then:raised sufiiciently for it to clear the valve *53,V whereupon the latteris turned into the position shown in Fig.V 3 and air .exhausted Jfromthe. can' through the valve. 1 The punch-bearing member is thencompletely withdrawn from the outlet 19', as indicated in Fig. 1, andthe valve is then returned toits position shown in Fig.- 2, therebycausing the by-pass to communicate withV the receptacle and with the canthrough the outlet, and the material is permitted to flow' by gravityand atmospheric pressure from the receptacle into the-exhausted can. The

iiow is stopped by again lowering the punch v into the outlet19y asshown in Fig. 3, and the G5 valve v53 is oscillated back to its normalposition closing said outlet. The filled can is then lowered and removedand the cycle indefinitely repeated.

It will be understood that, in usual practice, the heads of the canscontain a relatively small central opening, or aperture, of usually notto exceed one thirty-second of an inch in diameter, such opening beingillustrated in Fig. 4. But such opening is, although preferable, notessential, the operative end 48', of my punch-bearing member 48 beingcompetent to puncture the head, as Well as to enlarge such opening,-thecross sectional diameter of the punch in this instance being say aboutone-sixteenth of an inch.

The construction and operation are such as to result in the properexhausting and charging of a can by a comparatively unskilled operatorand through a relatively minute opening more expeditiously,economically, hygienically than heretofore.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent is the following, viz

l.- In apparatus for charging a fiowing material into a container, areceptacle for the material having adjacent its bottom a downwardlydelivering outlet; a reci rocable valve member within said reeeptaclecoperating with said outlet; an oscillatory valve below said receptaclealso eoperating with said outlet, and containing an air-duct and also aby-pass for the material, and means to oscillate said last mentionedvalve and thereby bring said air-duct and said by-pass alternativelyinto communication with said outlet.' Y

-2. In apparatus for charging a flowing material into a container', areceptable for the material having adjacent its bottom a downwardlydelivering outlet; within said receptacle a movable valve membercoperatable with said opening to close it; and a spindle valve disposedand oseillatable transversely of said outlet and containing an airductand also a by-pass for the material, said by-pass and air-duct beingalternately communicable with said outlet according to the oscillationof said spindle valve.

3. In apparatus for charging a owing material into a can, a receptaclefor the material having adjacent its bottom a downwardly extendeddelivery outlet;` a valve in said outlet movable therein and containinga by-pass for the material and an air-duct; a punch bearing memberreciprocable within said outlet, said by-pass, and said can; means toturn the valve so that the by-pass communicates with the receptacle andthe can, and alternately so that the air-duct communicates with the canthrough a part of said outlet; and means to reciprocate thepunch-bearing member while the by-pass and outlet are in communication.

With said can through said outlet according A to the positon'nto whichsaid spindle valve is rotated; and means to reciprocate thepunch-bearing member While `tlne bypass and outlet are in communication.

5. In apparatus for charging a flowing material into a can, a receptaclefor the material 'having adjacent its bottom a down- Wardly extendedoutlet; a spindle valve dis* posed and oscillatable transversely of saidoutlet and containing an air-duct and also Y a by-pass for the material,said by-pass and air-duct being alternately communicable with saidoutlet according to the oscillation of said spindle valve; and apunch-bearingmember advanceable from said receptacle into the can whensaid outlet and bypass are in communication.
